OPERATING INSTRUCTIONS
NOTE: See pages 6-9 for part numbers and illustrations of the 5373 as indicated in instructions below.
Prior to testing:
1. The tubes to be tested should be cleaned and any loose deposits or scale should be removed. If
the tubes have not been cleaned, any foreign materials present may be ejected during the testing
operation and may damage the test guns or injure the operators.
2. The operators should always wear safety glasses or a face shield when testing with the 5373 or any
type of pressure test guns.
3. If the tubes have been acid cleaned please check with Elliott Customer Service regarding the
compatibility of the test gun seals with the cleaning agent. Different types of elastomer seals are
available as replacements.
4. Make sure the test guns have the correct size Replacement Seal and Washer Set (2) for the tubes
being tested. The seals and washers are considered to be correctly sized if the OD of the seal is
between 0.02” to 0.06” (0.5mm to 1.5mm) smaller than the actual tube ID. Using seals that are too
small may cause any of the following: premature seal wear, jamming of the test gun in the tube, or
expulsion of the test gun from the tube end. Replacement seals for the 5373 testing guns can be
manufactured for any tube ID from 0.28” to 1.23” (7.1mm to 31.3mm). For tube ID’s larger than 1.23”,
refer to Tech Manual TM-11 for information on the 5373A Test Gun Package. The procedure for
replacing the seal and washer sets is outlined on page 5.

OPERATING INSTRUCTIONS (CONT.)
Testing Procedure:
Never actuate the injection gun unless the seal assembly is installed within the proper ID tube as the
washers could be forced into the seal ID.
The 5373 Tube Testing Guns come as a set. This set is comprised of: an air injection gun and a
plugging gun. The air injection gun can be differentiated from the plugging gun because it incorporates
the air control valve (10) and bleed valve (12). The plugging gun is a slave to the injection gun and will
not operate without it.
1. Attach air supply to the air injection gun. The 5373 test guns will be operational on plant air supplies
ranging from 40 to 125 psi (2.7 to 8.6 Bar) at a minimum of 5 cfm. If testing tube ID’s from 0.28 to 0.48”
(7.1 to 12.3 mm) the regulator assembly is required. Install regulator assembly (14) with arrow pointing
towards gun onto reducing nipple (11) leak tight and attach air supply to regulator input. For tube ID’s
from 0.28 – 0.48” adjust regulator to 40 – 60 psi (2.7 to 4.1 Bar) by rotating adjustment knobs while
viewing gage.
2. Insert the air injection gun into one end of the tube to be tested and the plugging gun into the other
end. Apply enough pressure to seat the back-up washer (3) rmly against the end of the tube. Maintain
this pressure throughout the test.
3. After making sure that the plugging gun operator is ready, press the air control valve (10) on the
injection gun and hold until the reading on the pressure gauge (7) stabilizes.
4. Release the button on the air control valve (10). It will automatically return to the closed position
isolating the tube being tested. The tube is now under pressure.
5. Both injection gun and plugging gun operators should observe the pressure gage (7) on their
respective guns. Any decrease in the pressure indicted on the gauge (7) will indicate a leaking tube.
6. Press the bleed valve (12) on the injection gun to bleed off the air pressure in the tube and air cylinders
and to relax the seals.
7. Remove the test guns and move on to the next tube. Mark each leaking tube encountered for repair.
The total operation should be completed in 5 to 10 seconds. Your actual testing time will depend on
the amount of time you choose to hold the test pressure.
8. Repeat steps 2 through 7.

OPERATING INSTRUCTIONS (CONT.)
Installing Replacement Seals:
Replacement seals for the 5373 guns are supplied with the corresponding size washers. Always
replace the seals and washers on both guns at the same time. (See chart on page 9 for seal selection.)
1. Remove the locknut (1) from the end of the support tube (4) and set it aside.
2. Remove the Seal and Washer Set (2) from the support tube (4). Discard if worn. Under optimum testing
conditions you should be able to test between 100 to 500 tubes per replacement Seal and Washer Set.
3. For replacement Seal and Washer sets of the same size, install on existing support tube (4). If you are
changing the Seal and Washer set to a different size, keep in mind that the support tube assembly
(5) may be required to change as well. To replace the support tube assembly, refer to the procedure
outlined below.
4. When replacing the locknut (1) on the support tube (4) do not use a wrench, screw it on nger tight
only. A small space between the locknut, seal and washer set, and back-up washers is normal.
There will be enough stroke in the air cylinder to compensate for this space.
Replacing the Support Tube Assembly:
The 5373 test guns are originally shipped with three sets of support tube assemblies (5). These
support tube assemblies will allow you to test tubes with ID’s from 0.28” to 0.48”, 0.49” to 0.83” and
0.84” to 1.23” (7.1mm to 12.3mm, 12.4mm to 21.2mm, and 21.3mm to 31.3mm respectively).
1. Remove the Seal and Washer Sets (2) as outlined above.
2. Using an open end wrench on the wrench ats provided on the piston and a pipe wrench on the
support tube (4) gently unscrew the support tube from the piston inside the cylinder.
3. Choose the correct size support tubes for the tube ID being tested. All three sizes of support tubes will
t into the piston of the test gun. Use Never-seize or similar product to lubricate and seal the threads.
Do not over tighten the support tube.
4. Repeat steps 1 thru 3 for the remaining gun.
5. If testing tube ID’s from 0.28” to 0.48” (7.1mm to 12.3mm) thread the regulator assembly with arrow
pointing towards gun onto reducing nipple leak tight.
6. Prior to replacing the Seal and Washer Set (2) and the Back-up Washer Set (3) inspect the support
tube for scars left from the replacement procedure. File smooth if present.
Other Replacements and Repairs:
Under no conditions should you attempt to service the air cylinders. Any attempt to perform service
on the cylinders may void any and all remaining warranties, implied or otherwise.
